IMPROVEMENT IN eRAllKi-lauvolaas.`

` Specication forming part of Letters Patent No. 222,060., datedNovember 25, 1879; application iiled March 3, 1879.

To all whom it may concern:

Be it known that I, SYLvANUs D. LocKn, of Hoosick Falls, in thecounty ofRensselaer and State of New York, have invented new and usefulImprovements in Automatic Binders, of which the following is aspecification.

This invention relates to that class of automatic binders wherein thegavel is taken from a receptacle and separated from the stream of grainflowing into the same and bound with successive intermittent movementsof the parts.

The gavel is gathered, separated, bound, and discharged by positivemovements dependent upon the rotation of a single shaft.

This binder is adjustablev longitudinally, as to the delivery apparatusof the harvester, by means of a rack and pinion operated by a handleverand secured by a lock upon the same, as heretofore shown in my patents.The grain is cutand delivered to the receptacle of the binder bysuitable mechanism. (Not shown herein.)

That others may fully understand my invention, I will particularlydescribe it, having reference to the accompanying drawings, wherein- HFigure l is a perspective view of my machine. Fig.2 is an end elevationofthe same. Fig. 3 is a sectional elevation of the same. Fig/i is alongitudinal section.v Fig. 5 is a section on line m .r of Fig. 4; Fig.6, detail of binder'arm driving-gear. Fig. 7 is a detail ofthebinder-head. Fig. 8 is a perspective of the gathering-arm andstop-plate. Fig. 9 is a perspective of spool for binding material. Fig.l0 is a section of the same. Fig. ll is the binder-slide lock. Fig. l2is a rear elevation of my machine.

A is a part of the harvesterframe, and B is the receptacle of thebinder. G D is the rack and pinion whereby the binder with itsreceptacle is secured longitudinally on the ways E F, to adapt it tostraw of different lengths,

. and G is the hand-lever whereby said pinion is rotated.

H is the operative shaft, turning in stationary boxes mounted upon thepermanent frame ofthe harvester. At or near one end of said shaft thereis a sprocket or other suitable wheel, I, whereby motion from the primemover is received.

The binder ymechanism is supported by a suit-able frame-work, (shown inthe Idrawings,) but to which I do not propose to coniinemyself.

J is the main shaft of the binder, mounted in suitable bearings. Theshaft J is provided with a sprocketwhecl, K, which is mounted upon saidshaft, and brought into operative engagement therewith by means of aclutch, L, which is controlled by an ordinary shift-inglever.

Upon the shaft J, about the center of the binder, there` is a loose hubwith one or more curved arms, M, in a plane perpendicular to the axis ofsaid shaft. The curvature of `these arms corresponds to the curvature ofthe receptacle B, and in their revolution they approaoh the under sideof said receptacle, and pass upward through a median slit therein,thereby separating the iiowing stream of grain and raising the gavel ontof the receptacle to be bound. There are also mounted upon said shaft,and adjacent to said hub, a spur-gear and two segment-gears, which atthe proper times actuate the twisting and cutting mechanism.

` The devices described herein and designed to be covered by this patentmay operate with any suitable device for securing the handmaterial. Manysuch devices are known, and I therefore do not propose in this patent torestrict myself either as to the material to be em ployed for the bands,nor as to the devices whereby saidpband may be secured.

The special devices for securing the bandwire and severing it at theproper moment which I have devised with reference to this particularmachine I propose to make the subject of a separate patent, andtherefore make no illustration thereof in this patent.

Upon the shaft H thereis asprocketwheel, N, which slides upon saidshaft, and is prevented from turning thereon by a spline and feather, orother proper device for the same purpose.

A chain passes from the sprocket-wheel N over the wheel K, tocommunicate motion, and they are kept properly in line with each otherwhen the binder is moved upon its ways by means of a traveler, O, whichis hinged to the binder-frame, so that it may be turned back outofengagement with said pinion, if desired.

At one end of the shaft J there is a segment-gear, P, of peculiarconstruction. It has two Vsets of gear-teeth, equal in number,

but not placed opposite each other on the pe-A riphery of said wheel.Intermediate between said sets of gear-teeth there arelaterally-projecting han ges p, the outer surfaces of which arecoincident with the curved line upon which the teeth are set. The wheelP is the driver for the wire-carryin g arm Q.

A pinion, R, having the same number of teeth as the wheel P, is mountedupon a stud above said wheel, and so as to mesh therewith. 0n the faceof said pinion, and projecting radially beyond vits periphery, there aretwo plates, r, having the outer edges concave upon arcs of equal radiuswith the flanges of the wheel P, so that -in certain positions saidconcave will engage with said flan ges, and

while the wheel P may continue to rotate the pinion R will berestrained. The effect of this device is to give to the pinion R anintermittent semirotation with unequal intervals of rest.

When the teeth of wheel P engage with the teeth of pinion R the flange19 and plate r, referred to, go out of engagement, and, the teeth of thesegment on P being equal to half the number of teeth on R, the lattermoves half a rotation, when the plate and flange again engage andrestrain the. pinion until again engaged.

An eccentric stud upon the pinion R serves as an attachmentfor aconnecting-rod, S, which actuates the rock-shaft T, whereon thewireearrying arm Q, is mounted, and the unequal intervals between thesegments on the wheel P operate to give a lou ger rest to said arm Qwhile thrown forward, and whilethe band-securing devices are operating,than while thrown back to permit the advance of a new bundle.

The intermittent movement ofthe arms M is produced by means of asegment-gear, U, which is fast upon the shaft J, and a pinion, V, withwhich it intermittently7 engages, and thereby transmits motion to aspur-gear, W, attached to the hub of the arms M.

The upper part of the receptacleBis a semicylinder divided at its middleto permit the passage ofthe arms M; but the opening through which theypass is permanently closed by a cylindric ange upon the arms M, so thatstraw, &c., is excluded.

The wire-carrying arm Q has simply a friction-roller at its end, overwhich the wire travels. The end of the wireis griped in the twistingmechanism, and is drawn from a spool conveniently located; but no morethan the exact quantity to encircle the bundle then being bound is underany circumstances withdrawn, so that no slack-take-up device isrequired.

As the arms M rotate the lowermost one separates the stream of grain,and carries the bundle so gathered upward against the binding-wire a andthe spring-arms b b, by which it is supported, and,in a measure,compressed. The arms M having come to rest, the wire-carrier Q,advances, carrying the wire a around the sheaf and into the twister,where itis twisted and severed, and said arm then retreats. The

next forward movement of the arms M carries the bound bundle over theapron c and discharges it while a new bundle is being elevated to bebound.

The convenient location and arrangement of the wire-spool is ofconsiderable importance with machines of this kind, and the tensionapplied to the same'should also be of the simplest kind. Heretoforesprings have generally been employed in one wayor another; but they arealways objectionable because of their liability to break, and therebytemporarily disable the machine.

I have therefore mounted my spool upon a stand, d, projecting from theframe of the binder directly in front of Y the twisters, so that thewiredraws straight from the spool to the wire carrier and twisters. This isa great advantage, because when its direction is changed by passing overguide-pulleys, Src., it is not only more liable to derangement andbreakage, but additional power is absorbed in overcoming resistance dueto additional bearingsurfaces and change of direction. The spool standor bracket d has two bearings to receive the spindle c, upon which thespoolis mounted; or said spindle may be hinged at one end, or otherarrangements may be made so that a part may be conveniently displacedfor the placing or displacement of the spool.

The tension consists of a broad strap, f, of leather or other flexiblematerial, one end of which ma-y be secured to the frame, and the otherend may hang free` over the spool and resting upon it. The frictionbetween the binding material upon the rotating spool and the surface ofthe ixed strap produces the required resistance to the rotation, knownas tension,7 and, as is apparent, the friction may be very readilyincreased or diminished by wei ghts attached to the free end of saidstrap.

When the spool is full and the leverage of draft is longest, becauseremoved to the farthest point from the center, the point of frictionalresistance will be equally removed from the center, and as the bindingmaterial is discharged these conditions of leverage will simultaneouslyand equally recede toward the center, so that with an equal weight uponthe strap f the tension will be practically uniform from the full spooldown to the time of entire discharge.

It is desirable that the binder shall be bodily removable from thereaping-machine, and I therefore make it as a complete structure and.arrange suitable fastenings, whereby it. may

be readily attached or detached from the reaping-machine.

Behind the piece A, which is a part of the frame of the reaping-machine,there is a groove or way in which the front sill, U', of thebinding-machine is fitted, so that it may slide back and-flth thereinwhen the" binder is moved endwise, for the purpose of adaptingthemachine t0 the length of straw being bound.

The Tem Sill, V', of the binder is adapted to aV pivoted arm to servesto retain the latch W in i position by locking into holes prepared forthem.

Having described myinventon, whatIclai'm as new is y l. Thedriving-shaft H, provided with the wheel N, mounted thereon with aspline and feather, combined with the hinged traveler O, attached to thesliding` binder-frame, to carry said wheel with said frame into changeof adtusttlrlnent or be disengaged therefrom, as set 2. The receptacleB, the upper part of which is a semi-cylinder divided transversely atthe middle, combined with arms M, provided with a cylindric flange Jing,m, to permanently close the opening* between said eylindrical parts ofthe receptacle.

3. The shaft J, provided with the fixed segment-Wheel U, and the longpinion V, in mesh therewith periodically, combined with the spurgear W,constantly in mesh with said pinion and rigidly attached to the hub ofarms' M, whereby they are intermittently rotated.

4. The latches W', pivoted to the permanent frame and swinging over thesill V', to keep the same from accidental displacement, combined with.the hinged locking-arms fw, as set forth.
